What to do for Spray Foam Smell?


Probably worth a call to the EPA to see if they can suggest appropriate testing.

What to do for Spray Foam Smell?


Finally, spoke with someone at Dow who I felt comfortable with. He had a recommended cleanup procedure. I passed along the procedure to the installer and requested it be performed prior to reapplication. I'll post some pictures tonight.

Man this has been a whirlwind the last few days. I'd recommend anyone who considers this do some research before they come to any conclusion regarding the suitability of products of this nature in their home.

I think we actually have a plan to get the family back in the home over the weekend.

What to do for Spray Foam Smell?


insane! after having that happen you did it again? No way would I ever use spray foam to insulate a home. the ROI on it is 30 plus years before it pays for itself. plus it is toxic as heck.

Well at this point we were pretty much stuck. The rest of the basement was already sprayed. This area was probably 10% of what we had. What choice did we have at that point other than trying to remove everything?

In any case, I would say there is a strong possibility we move. I'm not sure I'll ever sleep soundly in this house again as long as my wife and kids are here.

I agree with you that SPF has some toxic elements but there are applications where it works great and will not take anywhere near 30 years to pay itself off. Not sure where that math came from.

Flash and batt is very effective and minimizes its use to predominantly air sealing benefits.

What to do for Spray Foam Smell?


Not to be argumentive, I just look at some of the "air tight" homes I have done remodeling on and mold abatement. on homes built over the last 15 years. were poly was placed over the insulation there was mold growth on the back of the sheetrock, roofs and walls rotted from water damage were spray foam was used i.e. the HO never knew there was a leak because the foam held the water back. but when I have done remodels in older homes were there is none of this "air sealing" done there is no mold or rot. My question and it is just to toss out there. are we making homes that are prone to other problems down the road? and how much of a savings is it really? the dept of energy has never said how much one will save. Just that they say "Can save up to" x amount. Do we really save that amount??

Nailbags,

I don't disagree with you. The fact that foam is an air barrier would naturally lend itself to trap moisture if there was an interior vapor retarder (poly).

Who is putting poly over a wall that gets spray foamed? This is terrible application to put it mildly.

While its a recipe for disaster, how do you blame the foam for that?

A home that leaks a ton of air will normally stay dry but also cost a bunch more to heat and cool.

OC SPF is water permeable and a leak will show through the foam at some point.

I don't think we should build a bunch of homes that use a bunch of energy just to keep them dry as a result of poor application.

Anyone that puts a poly over a wall with foam in it should have their butt kicked and certainly prevented from building or remodeling a home.

Nailbags,
"Do we really save that amount?? " I think the research clearly shows that you do. http://www.buildingscience.com/docum...ypes/bareports

"It's a long report but I think this gets to your question (pg87)
For the 27 comprehensive DER projects for which sufficient post-retrofit energy use data were available the mean reduction in total site energy use achieved is 58% with the site energy use reductions for individual projects ranging from 29% to 89%."


But it depends on a lot of variable, it has to be done right and you have to have a long term view.

What to do for Spray Foam Smell?


I was down in the basement today finishing up some last minute things for drywall. I noticed there is a definite difference in color between the two foam applications. The stuff done the first day is white in color, while the the reapplication was yellow. In one of my previous posts you can see the difference.

Sounds like white can be a b-rich indication and yellow can be an a-rich indication. Is there a band where each is acceptable? What color is desireable? Dow Froth-Pak sealant was used on the walls.

Here are a couple of photos. The whiter shade is the old foam and yellower is the new. They are clearly different. Not sure how critical the color is?
